RICHARD W. PEER, ROCHESTER, NEW YORK, ASSIGNOR OF ONE-THIRD TO AUGUST FINOK, JR., OF SYRACUSE, NEW YORK.

MACHINE FOR LASTING BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 737,766, dated September 1, 1903.

Application filed March 28, 1902.

To all whom it may concern:

Be it known that I, RICHARD W. PEER, a citizen ofthe United States, residing at Rochester, in the county of Monroe and State of New York, have invented new and useful Improvements in Machines for Lasting Boots or Shoes, of which the following is a specification.

This invention relates to machines for lasting boots and shoes, and especially for lasting uppers prepared for lasting by securing a wire to the upper by means of zigzag stitches, the upper so prepared forming the subjectmatter of a separate application for Letters Patent of the United States filed by me March 1, 1902, Serial No. 96,216.

My improved uppers are prepared for lasting by attaching a draw-wire to one face of the upper, near the edge thereof, by two threads, one of said threads located upon the same face of the upper as said draw-wire and passing diagonally across said draw-wire alternately from one side to the other thereof and interlocking with a second or shuttle thread located upon the opposite face of the upper, said second thread also passing diagonally across said draw-wire from one side to the other thereof, but upon the opposite side of the upper to that upon which said drawwire is located. The upper prepared for lasting,as hereinbefore set forth, is placed upon a last and secured, preferably, by a single tack to said last. The two free ends of the wire are then drawn lengthwise of the last and finally twisted one around the other, or the twisting of the wire may take place simultaneously with the drawing of said wire lengthwise of the last. The wire being thus drawn lengthwise of the last draws the upper over the edge of the last, plaiting the same around the too or heel, as the case may be, and holding the upper firmly in position after the ends of the wire have been twisted as set forth. In the case of very heavy leather it is sometimes desirable to assist the wire in drawing the upper tightly over the last by means of wipers for the toe or heel or both.

Myinvention consists, in a machine forlasting boots and shoes with uppers having a 50 wire attached thereto, of a support for a last,

a wire-holder, and means whereby said wire- Serial No. 100,421. (No model.)

holder may be rotated about an axis extending longitudinally of said last.

, My invention again consists in the instrumentalities hereinbefore set forth, in combination with means whereby saidwire-holder may be moved lengthwise of said last.

The invention finally consists in the com bination and arrangement of parts set forth in the following specification and particularly 6o pointed out in the claims thereof.

Referring to the drawings,Figure 1 is a front elevation of my improved machine for last ing boots and shoes. Fig. 2 is a side elevation of the same, taken from the right-hand side of Fig. 1. Fig. 3 is a horizontal section taken on line 19 19 of Fig. 1. Fig. 4 is a section, partly in elevation, taken on line 20 20 of Fig. 1. Fig. 5 is an enlarged end elevation of the rotary wire-holder and a portion of its supporting-lever. Fig. 6 is a detail end els vation of the rotary Wire-holder. Fig. 7 is a View similar to Fig. 6, showing the sleeve on the wire-holder turned downwardly to hold the ends of the wires in said wire-holder. Fig. Sis an enlarged section taken on line 24 24 of Fig. 7. Fig. 9 is a detail front elevation of the'bell-crank lever upon which the wire-holder is supported. Fig. 10 is a plan view of a last with an upperlasted there on by the machine of my invention.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 30 is a base-plate to which a column 31 is fastened. Said column projects upwardly and the upper portion thereof is curved backwardly from the upper end, terminating in a head 32, provided with a face-plate 33, adj ustably fastened thereto by bolts 34. The rotary wire-holder and the mechanism by means of which the wire extending around the upper of the shoe, as hereinbefore set forth, is drawn up and the ends twisted are adjustably supported, as hereinafter set forth, upon the face-plate 33. The last 35 after having had the upper 36 placed thereon, said upper being held in position on the last by a tack at the heel portion thereof, is placed upon a heel-post 37, A with the toe of the shoe resting upon a toe- :00 rest 38. The heel-post 37 is supported upon the column 31 and constitutes a last-support,

and the toe-rest is supported upona standard 39, pivoted at 40 to the base-plate 30.

A toe-wiping mechanism 41 is supported upon a standard 42, pivoted to the base-plate 30. A heel-wiping mechanism 43 is supported upon a standard 44, pivoted at 45 to the base-plate 30. i The heel-wiping mechanism is adjusted bodily toward and away from the last or to accommodate different lengths of last by means of an adjusting hand-nut 46, having screw-threaded engagement with a screw 47, pivoted at 48.to an ear 49 upon the column 31. The hand-nut 46 is connected to the standard 44 by two screws 50 50, screwed into said standard upon opposite sides thereof and engaging in a suitable manner at their inner ends the hand-nut 46. The toe-wiping mechanism is adjusted bodily toward and away from the last or to accommodate varying lengths of lasts by a hand-nut 53 and screw 54, pivotally connected at 55 to an ear 56 upon the column 31. The hand-nut 53 is rotatably connected to the standard 42 by screws 57 in the same manner as the standard 44 is connected to the hand-nut 46. I

The standard 39, upon which the toe-rest 38 is supported, is adjusted lengthwise of the last by a hand-nut 58, having screw-threaded engagement with the screw 54 and being rotatably connected to the standard 39 by the screws 59 engaging in a suit-able manner at their ends with the hand-nut 58. The heads of said screws engage vertical sliding blocks 62, arranged to slide vertically in grooves 63, provided in the standard 39.

The last-support 37, Fig. 1, is turned of a smaller diameter at the end thereof than the main portion to form a last-pin 64, and the last 35 is placed upon said last-pin when the shoe is about to be lasted. The last-support 37 is bifurcated at to pass the screw 47 and is forked at its lower end and pivotally connected by a bolt 173 to a vertical screwthreaded shaft 66, arranged to slide vertically in bearings 67 67 upon the column 31 and provided at its lower end with a collar 68, fast to said shaft 66 and flatted off upon the lefthand side, Fig. 1, where it bears against the face of said column to prevent said nut and the shaft 66 from rotating. The cylindrical upper portion of the last-support 37 slides vertically in a flexible rubber washer (not shown) held in a bracket 70, fast to the column 31 and having a ring 71 fast to the top thereof to prevent said rubber washer from being pushed upwardly out of the bracket 70.

The shaft 66 has screw-threaded engagement with a nut 72, held between the bearings 67 and havinga spiral gear 73 out upon its periphery. The spiral gear 73 meshes into a spiral gear 74, fast to a horizontal shaft 75, Fig.1, said horizontal shaft being provided at its outer end with a crank 76, provided with a handle 77. By rotating the shaft 75 and gear 74 by means of the crank-handle 77 the spiral gear-nut 73 will be rotated and will thus force the shaft 66 up or down, as the ver 146.

case may be, raising and lowering the lastpin 64 and, the last which rests thereon to the desired height.

To hold the toe of the last firmly in position upon the toe-rest 38, I provide a springclamp arm 78, Fig. 1, the forward end of which bears upon the last or upon the inner sole of the shoe placed thereon, the rearward end thereof being supported upon the standard 39. The toerest 38 has a vertical cylindrical shank 92, arranged to slide vertically in the standard 39 and being prevented from rotating by a pin 93, arranged to slide in a vertical slot formed in said standard.

In Fig. 10 I have shown a portion of the upper of the shoe provided withja wire 96, extending around the fore partand a portion of the shank of said upper 36. Said wire is attached to the upper, near the edge thereof, by diagonally disposed or zigzag stitches 97, said stitches being formed by a lock-stitch machine, so that there are stitches upon the underneath surface of the upper, as well as upon the upper surface thereof, extending diagonally across the wire 96. The free ends 98 98 of the wire 96 extend, preferably, through eyelets 99, fast to the upper 36.

After the shoe has been placed upon the last-support 37, with the toe resting upon the toe-support 38, the toe and heel of the upper are drawn up over the last by the toe-wiping mechanism 41 and the heel-wiping mechanism 43, respectively, said toe and heel wiping mechanisms being of any desirable construction and well known to those skilled in this art. During the operation of wiping up the toe and heel, or after said wiping operation has been completed, the free ends 98 of the wire 96 are drawn toward the right, Fig. 1, and finally twisted together, or while they are being drawn to the right are simultaneously twisted together by means of the wireholder 132. Said wire-holder consists of a rotary cylindrical pin 133, having a slot 134 extending laterally thereacross and inwardly slightly beyond the center thereof, where it is intersected by another slot 135, extending lengthwise of said cylindrical pin. The forward end of the pin 133 is conical in shape and is shouldered to receive a locking-sleeve 136, having a slot 137 extending lengthwise thereof. The pin 133 is provided with a cylindrical shank 138, having a hand-wheel 1.39 fast to one end thereof, said shank 138 being adapted to rotate in a bearing 140, provided in the front end of a rocking holder 141, said rockingholder having a cylindrical shank 142 'extendin g rearwardly and adapted to rock in a bearing 143, provided in a horizontal arm 144, extending forwardly from the lower end of the vertical arm 145 of the three-armed 1e- The rearward end-of the shank 142 is shouldered to receive a nut 147 and is provided with friction washers 148, bearing against the face of said nut for the purpose of preventing the holder 142 from rotating too freely. The lever 146 is provided with a roll 154, adapted to rotate in the enlarged portion 155 of the slot 152. The lever 146 has, in addition to the vertical arm 145, two short arms 156 157, extending in diametrically opposite directions from the pivotal center 149 and having a slot 158 provided in the rear faces thereof and extending lengthwise of said arms 156 and 157 to receive a friction- .roll 159, supported upon the head of a screw 160, fast to a vertically-sliding block 161. The block 161 slides in ways 162, provided in the head 32, and is connected by a treadlerod 163 to a treadle 164, pivoted at 165 to a bracket 166, fast to the base-plate 30. The treadle 164 is held upwardly by a spiral tension-spring 167.

Assuming the parts to be in the position shown in Figs. 1 and 3, with the upper drawn up over the last at the toe portion by the wipers, the operator takes the two free ends 98 of the wire 96 and passes them through the slot 137 in the locking-sleeve 136 into the slot 135 in the cylindrical pin 133, turning the ends over in the lateral slot 134, and drawing them down in the V portion 168 of said slot, as shown in Figs. 5 and 8. Having thus secured the free ends of the wire 96 in the slot 135, the locking-sleeve 136 is turned from the position shown in Fig. 6 to that shown in Fig. 7, thus securely locking the ends of the wire 96 to the rotatory holder 132. The operator now places his foot upon the treadle 164, drawing the sliding block 161 downwardly and, through the screw 160 and block 159, tipping the lever 146 upon its pivot-stud 150, carrying the vertical arm of said lever toward the right, Fig. 1, and drawing the wire 96 taut, and thus pulling the upper over the edge of the last around the fore part and a portion of the shank of said last. During the motion of the lever 146 toward the right, as hereinbefore described, the operator turns the hand-wheel 139 and twists the free ends 98 of the wire 96 around each other, thus securely locking the ends of the wire and holding the upper firmly upon the last. It will be seen that as the wire is being pulled taut, as hereinbefore set forth, the wire-holder is free to tip upon the pivotal shank 142, and thus the direction of pull of the wireholder may vary to conform to the natural conditions without forcing the upper upwardly away from the last. Having drawn the upper as taut as may be desired by the hereinbefore described movements of the wiper and of the wireholder, the operator disconnects the free ends 98 of the wire 96 from the wire-holder 132 and removes his foot from the treadle, whereupon the wireholder and the lever 146 are turned to the position shown in dotted lines in Fig. 1, and

the operator then proceeds to draw up and twist a second wire 169, Fig. 10, which is attached to the upper 36 by diagonal stitches and extends around the heel portion of said upper and a part of the shank portion thereof, the free ends 170 being carried through the eyelets 99, as in the case of the wire 96. To pull the wire 169 and twist the free ends 170 thereof around each other, the wire-holder 132 is moved toward the left in Fig. 1 instead of toward the right, as in the hereinbefore-- described operation of drawing up the Wire 96. The operator turns the rocking holder 141, together with the wire-holder 132, from the position shown in full lines, Fig. l, to that shown in dotted lines therein. He then loosens the nut 153, Figs. 1 and 3, and moves said nut, together with the pivotal stud 150, to the left-hand end of the slot 152, thus transferring the pivotal stud 150 from the right-hand side of the screw 160 to the lefthand side thereof, the lever 146 traveling with the stud 150 and the screw 160 and roll 159 sliding in the slot 158, formed in the rear face of said lever 146, to allow of this adj ustment. The operator now attaches the free ends of the wire 169 to the wire-holder 132, as hereinbefore described, and, placing his foot upon the treadle, depresses the sliding block 161, which, being connected to the arm 157 at the right of the pivot 150, tips said lever 146 upon said pivot, moving the vertical arm 145 to the left instead of to the right, as in the case hereinbefore described, and drawing the heel-wire 169 toward the left, the operator meantime rotating the wheel 139 and twisting the ends of the wire 169 around each other.

It will be seen that the lever 146 in its operation being tipped upon its pivotal center 149 by depressing the treadle, as hereinbefore described, constitutes a bell-crank lever, the pivotal center of which may be changed to opposite sides of the part by which said bellcrank lever is rocked, so that the direction in which said lever is rocked by a downward motion of said treadle may be reversed.

In order to hold the last and upper firmly upon the last-pin 64 and support 37, a spring clamp holder 171, Fig. 1, is provided, which partly encircles the heel portion of the last and is suitably fastened to the heel-wiping mechanism 43, the object of this clamp being to hold the upper firmly upon the last and to assist in holding the last upon the support 37 during the hereinbefore-described operations of wiping the upper over the toe l&

tached to the shank portion of the upper, upon the last, places the last upon the support 37, clamps the toe of the last and of the upper upon the toe-rest 38 by means of the clamp-arm 78, and then in case of shoes having an upper of heavy leather the toe and heel of the upper are wiped over the last by the toe and heel wiping mechanisms 41 and 43. The free ends of the wire 96 are then attached to the holder 132, the wire is drawn taut by depressing the treadle, and the free ends of said wire 96 are twisted around each other by rotating the hand-wheel 139. The free ends of the wire 96 are then detached from the holder 132. Said holder is rocked upon its horizontal pivotal center from the position shown in full lines, Fig. 1, to that shown in dotted lines therein. The pivotal center of the lever 14:6, upon which the wireholder is pivotally supported, is then adj usted from the right-hand side of the screw 160 to the left-hand side thereof, the free ends of the wire extending around the heel of the upper are attached to the wire-holder 132, and the wire-holder 132 is then moved toward the left, Fig. 1, drawing up the heel-wire by depressing the treadle, the free ends of said wire 169 being twist-ed by rotating the handwheel 139, as hereinbefore described. It the twisted portion of the wires is longer than is considered necessary, a portion may be cut off with pincers. After the shoe has been lasted, as hereinbefore described, the wiping mechanisms 41 and 43 are thrown back and the wire-twisting mechanism is thrown out of line with the shoe by depressing the treadle, the clamp-arm 78 is removed from the toe of the last, and the shoe is then removed from the machine by lifting it from the last-pin 64 and toe-rest 38.
